During the current period, 25 holes/1042 feet of diamond drilling to check on discrepancies with previous downhole percussion drillhole ore sample assays reported from the Lagoon area, plus 31 holes/2780 feet of exploratory/appraisal percussion...

Ongoing evaluation work undertaken by Austminex at the Mount Gunson copper deposit has included geological mapping, rock rippability testing by bulldozer, the conduct of IP surveys, a further campaign of infill and exploratory drilling (726 holes...

Two distinct types of sulphide deposits have been recognized. One is syngenetic with the host quartzite, and may thus also have formed elsewhere at various positions within it. The other type of occurrence was deposited below the water table from...

Drill holes from grid 6 520 000 to 6 521 000 mN and all eastings up to 707 000 mE; 6 521 000 to 6 522 000 and all eastings.

Known mineralization in the 2 areas was indicated by the IP results, so undiscovered similar mineralization should be detectable by reconnaissance surveys. Low apparent resistivities seen over Pernatty Lagoon due to salt water saturation of bedrock...

The proposal to mine 4 orebodies of the Mount Gunson copper deposit is examined with respect to plant design, capital and operating costs and estimated ore reserves. A sequence for stripping waste, stock piling oxide ores and mining sulphide ores is...

Drill holes include those of the 3-1-XP series, where X=1 to 262.

Results of testing to formulate an accurate specification of the mineral processing equipment requirements. The test results a showed wide variance between samples.

Results of testing to formulate accurate specifications for the concentration plant equipment. Impact crushing trials in either a plant or near to a plant-sized mill are recommended in order to evaluate the alternatives to primary and secondary...

Detailed IP traverses were centred on Austminex drillhole D-11, which intersected disseminated chalcocite with some chalcopyrite and minor pyrite.

Test surveys could not trace the lithic sandstone-quartzite interface beneath the Lagoon area, but traced the lithic sandstone-dolomite interface in the Main Open Cut area with good accuracy.

Copper extraction in percolation leaching was relatively slow because of the low porosity of the large rocks in the as-ripped ore. To obtain reasonable extraction rates, size reduction will be required. Agitation leaching of ground ore gave copper...

The geological and geophysical basis for determining that the ore reserves were sufficient to allow mining to start on the East Lagoon and West Lagoon orebodies at Mount Gunson is detailed in the subject reports, and the likely technical causes of...

The interpretation aimed at locating repetitions of Mount Gunson-type mineralisation.

Drill holes from grid : 6 520 000 to 6 521 000 mN, 707 000 to 709 000 mE.

Work included froth flotation, leaching, solvent extraction and stripping tests. Estimates of capital costs and operating costs were made for oxide and sulphide flotation plants and a more complex plant comprising acid leaching, solvent purification...
